+APM X-Gene SoC Ethernet nodes
+
+Ethernet nodes are defined to describe on-chip ethernet interfaces in
+APM X-Gene SoC.
+
+Required properties:
+- compatible: Should be "apm,xgene-enet"
+- reg: Address and length of the register set for the device. It contains the
+ information of registers in the same order as described by reg-names
+- reg-names: Should contain the register set names
These are not aligned properly...
Required properties:
- compatble : Should be "apm,xgene-enet"
- reg : Address and length of the register set for the device.
It contains the information of registers in the same
order
as described by reg-names
.....
+ "enet_csr": Ethernet control and status register address space
+ "ring_csr": Descriptor ring control and status register
address space
+ "ring_cmd": Descriptor ring command register address space
+- interrupts: Ethernet main interrupt
+- clocks: Reference to the clock entry.
+- local-mac-address: MAC address assigned to this device
+- phy-connection-type: Interface type between ethernet device and PHY device
+- phy-handle: Reference to a PHY node connected to this device
+
+- mdio: Device tree subnode with the following required
+ properties:
+
+ - compatible: Must be "apm,xgene-mdio".
+ - #address-cells: Must be <1>.
+ - #size-cells: Must be <0>.
+
+ For the phy on the mdio bus, there must be a node with the following
+ fields:
+
+ - compatible: PHY identifier. Please refer ./phy.txt for the format.
+ - reg: The ID number for the phy.
+
alignment... :-)
+Optional properties:
+- status : Should be "ok" or "disabled" for enabled/disabled.
+ Default is "ok".
+
+
+Example:
+ menetclk: menetclk {
+ compatible = "apm,xgene-device-clock";
+ clock-output-names = "menetclk";
+ status = "ok";
+ };
+
+ menet: ethernet@17020000 {
+ compatible = "apm,xgene-enet";
+ status = "disabled";
+ reg = <0x0 0x17020000 0x0 0xd100>,
+ <0x0 0X17030000 0x0 0X400>,
+ <0x0 0X10000000 0x0 0X200>;
+ reg-names = "enet_csr", "ring_csr", "ring_cmd";
+ interrupts = <0x0 0x3c 0x4>;
+ clocks = <&menetclk 0>;
+ local-mac-address = [00 01 73 00 00 01];
+ phy-connection-type = "rgmii";
+ phy-handle = <&menetphy>;
+ mdio {
+ compatible = "apm,xgene-mdio";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ menetphy: menetphy@3 {
+ compatible = "ethernet-phy-id001c.c915";
+ reg = <0x3>;
+ };
+
+ };
+ };
+
+/* Board-specific peripheral configurations */
+&menet {
+ status = "ok";
+};
